What does it take to be persuaded of truth?  The disciples were not easily convinced.  They may have followed Jesus, but they were not about to lose their own discretion and opinions.

Matthew 16:
 21From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, chief priests and teachers of the law, and that he must be killed and on the third day be raised to life.
 22Peter took him aside and began to rebuke him. "Never, Lord!" he said. "This shall never happen to you!"
 23Jesus turned and said to Peter, "Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men."

Peter fell into the trap that Satan still uses.  ‘When the coming reality goes opposite to what you believe should happen, resist the plan.’ 

At the surface Peter looks heroic.  He does not want to see Jesus suffer persecution and be put to death. 

But supposed good intentions became demonic when Peter began to rebuke Jesus and rely on his human wisdom.  The darkness lies in the idea that the plan of God can be replaced with a better way.

We need to guard our thoughts from thinking we can come up with a better plan than God spells out.  Jesus had told them that this must happen.  Peter had a hard time hearing ‘must happen’.  Peter also seemed to miss the conclusion Jesus gave.  On the third day He would be raised to life.

When the plans of God and the path ahead contain pain and suffering, we might miss part of the message. 

The disciples knew the fear of suffering and death.  They did not know the full hope of resurrection.  The Devil’s trap gets you to miss out on where God is ultimately leading and instead get you to look for a way to avoid the necessary hardships.
